Previous research on the effects of pregnancy on multiple sclerosis (MS) is somewhat flawed, and well-controlled, well-designed studies are needed to validate trial findings. In general, pregnancy appears to have a protective effect on MS course, with fewer, less severe relapses, especially in the third trimester. The exacerbation rate is increased in the first 3 months after delivery, but the overall relapse rate is no different to that observed in non-pregnant MS patients. A woman's past history of relapses may be the best indicator of clinical course during and immediately after pregnancy. Pregnancy does not appear to affect the long-term course of MS.

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
